CAR-AXLE LUBRJICATO R.

j SPECIFICATION formingA part of Letters Patent No. 224,047, dated February 3, 1880.

`Application filed August 16, 1879.

To all whom it may concern:

Be it known that we, SAMUEL JSHIMER and GEORGE J. SHIMLER, of Milton, in the we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference belng had to the annexed drawings, makiuga A,part of this specification, and to the letters and figures of reference marked thereon.

Figure of the drawings is a longitudinal sectionalview of a car-axle box, showing our improvements applied thereto. Fig. 2 is a perspective view of the top bearing or brass. Fig. 3 is' a side view of a grooved pulley and fastening-bolt detached.

Thisinvention is designed as an improvement on the devices for lubricating caraxle A bearings shown in Letters Patent granted to us April 22, 1879, No. 214,592; and the main object of this improvement is to dispense with the horizontal grooves in the top bearing or brass, and reduce the bearing-surface to threefourths the diameter or to one-fourth ofthe circumference of the axle. We cast one or more lugs or projections on each side of the brass, substantially as shown in Fig. l of the drawings, which reach nearly to the center of the journal.

The outer walls of the lugs b are vertical and connected at the top, forming an integral part of thebrass or bearing A. These lugs or projections perform the threefold purpose of holding the brass in proper position in the car-box, holding the axle in place, and leading off the surplus oil from the journal back to the oil-well beneath. The edges c of the brass A are driven in between the lugs, and a groove, d, is cut or made nearly across the face of the bearing toward the rear end of the bearing-surface. The object of this groove is to prevent the waste of oil while the brass is wearing a seat when new. The sharp edges coming in contact with the journal B form a comparatively tight joint and scrape the surplus oil off, which forms into beads or large drops, which, being upheld by the revolving axle, as it leans to one side or to the other, come in contact with the side lugs and run down them and drop off` into the oil-well. i The shallow cross# groove d permits such oil as passes the edges of the brass and is scraped off by the bearing (which in a new brass is being formed in the center by the frictional wear of the parts) topass over to the other side before it reaches the shoulder on the axle at the rear end of the brass; otherwise it would work out to the wheel and he wasted.

At the forward portion of the brass are projections or overlappin g portions e, to rest lightly on the collar of the journal and conduct the oil to the bearing-surface.

To the outer end of the journal B is arranged, centrally, a wheel or pulley, or its equivalent, D, with an inwardly-inclined peripheralface having a series of recesses or depressions, f, to receive the links of an endless chain and to carrythe same. A washer, E, hangs loosely on the'bolt I, that holds the small pulley D, which drives the chain. The washer is provided with a counter-weight, or counterpo'ised, to prevent it from turning when the car is in motion. This construction and form of a pulley and washer is more Vdesirable than the other, as there is not always as much room in the front of the car-boxes as -there should be for the solid rimmed pulley, and with the washer standing still it isimpossible to throw the chain off the pulley. l

The oil-feed is substantiallythe same as set out in the Letters Patent above referred to. It is plain if the oil is once carried up it cannot get down over the axle, as that is moving and will carry it up continually. Therefore it must come down on the lugs or projections, of which there should be two or three on each side.

This brass is applicable to oiling or lubricating in the common way with cotton-waste. The lugs of the brass need extend drown no farther than is necessary to keep the journal IOO cantv-conveyer, consisting, essentially, of an endless chain running upon a pulley, or its 5. The car-axle brass hereinbefore described, having a narrow bearing-surface, and provided 15 With the side lugs orprojections and the transverse groove at the rear end, for the purposes set forth.

In testimony whereof We have hereunto subscribed our names.
